- - - - inkjet printer
        
        Inkjet produce a high speed quality output with presentable features. A nozzle for black ink may be all that’s needed to print text, but full-color printing is also possible with the addition of needed to print text, but full-color printing is also possible with the addition three extra nozzles for the cyan, magenta, and yellow primary colors. Using inkjet printing the color printing is also possible.
      - thermal printer
        
        {1} very high speed. {1} Laser printer is more expensive.
        
        {2} very high quality printing output. {2} cannot use to produce multiple copies a document in a single printing.
        
        {3} low noise printing operation. {3} There size are generally larger.
        
        {4} give good and high quality graphic quality.
      - lazer printer
        
        Laser prints are generally very high and very accurate.
        
        For high volume printing laser printers are considerably cheaper to run.
        
        Printing is fast so they can handle large volumes.
        
        Due to the technology used prints from a laser printer emerge from the printer dry to the touch.
        
        Disadvantages
        
        Buying a laser printer can be expensive when compared to an inkjet.
        
        Colour laser printers are significantly more expensive than a colour inkjet.
        
        Laser printers are larger and heavier as they need to contain the imaging drum and laser technology.
      - flat bed printer
        
        plotter can work on very large sheet of paper. {1}Plotter is slower in printing speed.
        {2} Plotter allows the same pattern to be drawn thousands of times. {2} they do not produce very high quality printouts.
      - impact printer
        
        The printer that prints the characters by striking the against ribbon and onto the paper are called impact printers.
        
        An impact printer makes contact with the paper. It usually forms the print image by pressing an inked ribbon against the paper using a hammer or pins.
        
        Impact printers are of two types:-
        
        How do the impact printer working
  - - - used by large organizations
      - tracking spce
      - High capacity
      - traking weather
- - - - In computers, a utility is a small program that provides an addition to the capabilities provided by the operating system
    - - it is a special piece of software which manages the general operation of the of the computer system
    - - More commonly known as a driver, a device driver or hardware driver is a group of files that enable one or more hardware devices to communicate with the computer's operating system. Without drivers, the computer would not be able to send and receive data correctly to hardware devices, such as a printer.
    - - In computer science, a linker is a computer program that takes one or more object files generated by a compiler and combines them into one, executable program
    - - a program that converts instructions into a machine-code or lower-level form so that they can be read and executed by a computer.
